FEEDING MECHANISM FOR FIBROUS MATERIAL Application filed August 30, 1917.

To all whom t may concern:

Be it known that we, FRANK L. FURBUSH and OsBoRN H. CILLEY, citizens of the United States, both residing at Westford, in the county of Middlesex and State of Massachusetts, have invented a new and useful Feeding Mechanism for Fibrous Material, of which the following is a specification.

This invention relates to a device for feeding fibrous material such as wool and the like to a drier, washer or other machine.

The principal object of the invention is to provide a device of extremely simple character for insuring the feeding of short fibers into the nip or bite of the feed roll or rolls. These short fibers do not ordinarily have sufficient carrying capacity to pass into the bite under the ordinary systems of feeding. By this invention they are caused to be fed along with the rest of the material so that the operation of the machine is efficient and uniform.

Further objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which-A Figure 1 is a longitudinal sectional view of a part of a feeding device with a preferred embodiment of this invention applied thereto, and

Fig. 2 is a plan with the feed apron and upper roll removed.

The invention is capable of application to types of feeding devices in which two feed rolls are employed, but we have shown it herein as applied to one in which the material is fed as usual over an apron 10 under a compression roll 11 into a space behind the fluted feed roll 12 which projects over a stationary iron feed plate 13.

At a convenient point on the machine power is imparted from a shaft 111 through two gears 15 to a shaft 16 having a crank or eccentric thereon for operating a link 17 which oscillates a lever 18. The lever is connected by a link 19 with a steel plate 20 to reciprocate the same. This plate is provided with guide pins 21 which work in ways 22 on the sides of the machine, the plate extending all the way across the same preferably under the slat conveyer 10. It

projects toward the bottom or feeding side of the roll 12 and into the space between this roll and the cooperating member with which it acts, in this case the stationary feed platel 13. The reciprocation of this plate tends to force all the fibers along together so that the short fibers will be caught in the bite of the feeding apparatus as well as the long ones.

The active edge of the plate 2O is shown as provided with teeth 23 for the purpose of enabling it to enter the stock better and to perform its function of pushing it into the bite more efficiently.

We have also provided a triangular wooden cross bar Q5 directly over the plate 20 and under the end of the apron conveyer. This is located in stationary position to prevent the fibers from moving backward as the plate 20 is drawn away from the feed roll.

From what has been said it will be seen that this is an exceedingly simple arrangement for this purpose, that it does not reduce the capacity of the machine in any way or take up any material space, but that it positively forces the bers into a position to be taken up by the feeding apparatus and insures both efiicient and uniform feeding of the fibers even when the stock is made up of fibers of widely different lengths and character.

Although we have illustrated and described only a single form of the invention we are aware of the fact that modifications can be made therein by any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore we do not wish to be limited to all thedetails of construction herein shown and described, but what we do claim is 1. In a feeding device for fibrous material, the combination with a feed roll, and a feed plate in position for receiving and supporting such material and having a concave discharge end located under the feed roll and substantially in contact with it, of a flat plate located parallel with the axis of the feed roll and havino' a forward toothed edge, and means for reciprocating said fiat plate in its own plane toward and from the bite of the feed roll.

2. In a feeding apparatus, the combination of an apron conveyor, a compressing roll therefor, a feed plate located under the space between the apron and the compressing roll, and a oiroumferentially fluted feed roll located over the feed plate, of a reciprocating plate having` a serrated edge located just over said feed plate and parallel there-- with, its serrations registering With the grooves of the feed rolls, and means for reoiproeating Said serrated plate toward the 1@ bite of the feed roll.

In testimony whereof We have hereunto affixed our signatures.
